Yeah, I mean, it's supposed to come off as showing off, right? "Sure, we're so crazy good, that we can take out name.com and linode just cause some script kiddies pissed us off, no sweat. Don't mess with us. And we're so in it for the lulz, that' SURE we'd take out linode and name.com just to get some script kiddies, and not bother trying to sell the CCs or anything."
Or, they're lying. I mean, they could be lying about the whole damn story, who knows (not me).
